At my studio we have like 15 people on our Leadership team and all of us teach classes. There have been times where we have more teachers than students in class. I know that we are all basically on the same page with our techniques and what we are doing. Personally if i see a student doing something and i correct them, i ask first waht any of the other Leadership members have told them then say what i think, i then go and ask the other leadership member and see why they said it that way. Worst comes to worst we ask our GrandMaster. It all works out in the end.
